Method Details [hide private]

_parseSetConnections(self, allow_compoents)

source code 
Manually parses the set connections from self
Returns:
tuple(MObjectArray(setapiobj), MObjectArray(compapiobj)) if allow_compoents, otherwise just a list(setapiobj)

componentAssignments(self, setFilter=fSetsRenderable, use_api=True, asComponent=True)

source code 
Parameters:
  • setFilter - see connectedSets
  • use_api - if True, api methods will be used if possible which is usually faster. If False, a custom non-api implementation will be used instead. This can be required if the apiImplementation is not reliable which happens in few cases of 'weird' component assignments
  • asComponent - If True, the components will be wrapped into the matching MRV compontent type to provide a nicer interface. This might slightly slow down the process, but this is usually neglectable.
Returns:

list of tuples(ObjectSetNode, Component_or_MObject) defininmg shader assignments on per component basis.

If a shader is assigned to the whole object, the component would be a null object, otherwise it is an instance of a wrapped IndexedComponent class

Notes:
  • The returned Component will be an MObject(kNullObject) only in case the component is not set. Hence you should check whether it isNull() before actually using it.
  • the sets order will be the order of connections of the respective component list attributes at instObjGroups.objectGroups
  • currently only meshes and subdees support per component assignment, whereas only meshes can have per component shader assignments
  • SubDivision Components cannot be supported as the component type kSubdivCVComponent cannot be wrapped into any component function set - reevaluate that with new maya versions !
  • deformer set component assignments are only returned for instance 0 ! They apply to all output meshes though
